From a bulls pov what do you think?

me and my gf have been together almost 5 years now and will shortly be moving into our first house together. I’ve been teetering on asking her to open/become a hotwif loads recently but always back out at the last second. it all started when we watched a tv show about exploring sexuality and she took a huge interest, since then she makes a point of pointing out guys she thinks are sexy (either in person or media). I think she knows it turns me on a little. we went to Amsterdam and saw a sex show and she loved the guys on there, she mentioned one of their cocks a few times while she was drunk that night! she’s talked about her exes cocks and I’ve started to gather she was very active sexually before she got with me (even mentioned I was one of 4 she had to choose from when we got together lol) I think she’s so sexy and our sex life is great we’ve recently discussed “spicing things up and trying new things” but I’m not sure if I just drop it on her. is now the time to pop the question now we will have our own home to play with?
